STOVE.

Application filed September 17, 1926. Serial No. 136,153.

This invention has general lreference to stoves and ranges which areadapted for use with gaseous or liquid fuels, but relates moreparticularly to means for regulating the distribution of heat, and thetravel of the products of combustion, in such stoves and ranges..

`A primary object of the present invention is to produce a stove orrange having associated therewith an oven which is adapted to be heatedby the passage therearound and therethrough of the products ofcombustion of gaseous or liquid fuel, improved means being provided forregulating the distribution, and the rate and direction of travel, ofthe heated gases.

A further object is to provide such regulating means which shall includemeans for by-passing a portion of the combustion products directly tothe discharge outlet from the stove or range, instead of following theusual indirect course to such outlet.

And a still further object is to provide means by which the opening orclosing of the oven door will automatically affect the rate anddirection of travel of the products of combustion, through the medium ofsaid lay-passing means.

The means by which the foregoing` and other objects are accomplished bymy invention, and the manner of their accomplishment, readily will beunderstood from the following description on reference to theaccompanying drawings, which depict a preferred embodiment of theinvention, and in which- Fig. 1 is a front elevation of a gas stovehaving my improvements applied thereto, parts broken away forconvenience of illus.- tration.

Fig. 2 is al section on line II-II of Fig. 1.

Fig. 3 is a top plan view ofthe stove shown in Fig. l, with parts brokenaway.

As shown in the drawings, in which simila-r reference numerals refer tocorresponding parts throughout the several views, the stove comprisesthe usual cast iron top 5, having removable lids 6; a sheet metal bottom7, end walls 8 and 9, back wall 10 and front wall l1; supporting legs12, of any preferred form; and an elevated shelf 13- A ysubstantiallyrectangular oven 14 is suitably supported within the body of the stove,in. such a way that intercommunicating open spaces are left between thetop 15 of the even the top 5 et the stove, between end 16 of the ovenand the adjacent end 9 of the stove, and between the bottoni 17 of theoven and the bottom 7 of the stove.n the end wall 18 of the oven beingextended downward to form an air-tight closure with the stove bottom, aportion of the back wall 10 of the stove constituting the vback of theoven, and the front of the oven, which is Hush with the front wall 11 ofthe stove. being provided with hinged door 19. The burner or burners 20,the number of which is optional, are located in a suitable positionbetween the end wall 8 of the stove and the end wall 18 of the oven.

The end wall 16 of the oven has a series of openings therein. as hasalso its bottom 17. and suitable dempers (not shown) preferably areprovided for regulating the effective areas vof slid openings. in somesuch manner as that shown and described in United State.. Letters PatentNo. 1.258.210, issued to me March 5. 1918. 'At the back of the stove. aflue 21,'closedat its lower end` entends vertically upward from at orbelow the level of the bottom of the oven to that of the top of thestove, and said flue communicates at its top with a suitable stack inwhich a damper (not shown) preferably is placed. Openings Q53 in thewall 1G. which constitutes the hack of both the stove and the oven.afford passageways for the heated gases from the oven into the flue 21.and thence into the stack. At the top of said flue. an opening Q4 in thewall 10 is fitted with a damper-hor 25. which surrounds said opening atall sides, and is provided vithva hinged damper 2G, adapted to close thepassagewa)Y leading from the interior of the upper part of the stovebody through said damper-box The lower edge of said damper is rigidlysecured to a pivot-rod 27, `which is mounted in suitable bearings 28formed upon or secured to the damper-box 25, one end of said pivot-rodhaving a lever arm 29 formed or secured thereon, and to the free end ofsaid arm is pivotally connected a rod 30, which extends in asubstantially horizontal position. at right angles to the longitudinalcenter line of the stove, through a suitable opening in the wall 10, andthrough a similar opening in the upper part of the frame for the ovendoor 19. Rod 30 is freely slidable in said two openings, its front endbeing in position to be engaged .by the 'upper portion of the door 19,and the lengths )osition the onlv means of access b* the 7 products ofcombustion to the flue 21, and thence to the stack 22, is through theopenings 23 in the bach wall of the oven. Hence,

, the hot gases inust pass from the burner or burners into the spacebetween the top 5 of the stove and the too 15 of the oven and be drawndownward by the stack draft into the interconnnunicating spaces betweenthe end wall'9 of the stove and the end 16 of the oven, and between thebottom of the stove and the bottom 1'? of the oven, said gases thenpassing tirough the openings in the walls 16 and 1'5" into the oven, andthence through the openings 23 into the flue leading to the stach. Uponthe oven door 19 being opened, the damper 26 will drop by gravity to itsopen position, and the staci draft will be effective upon the hot gasesto draw them through the damper-box 25 and into the upper part of theflue 21, as well as to draw some of said gases through the openings inthe end wall 16 and the bottom 17 into the oven, and thence through theopenings 23 into flue 21.

rlhere are two stages in the operation of a stove or range during whichthe invention described herein is of especial utility. When one or moreof the burners is or are lirst lighted, the stove body and the ovencontain air at room temperature, and considerahle time, and the use of aconsiderable quantity of fuel, ordinarily Vare required to `establishsuliicient draft to draw the hot gases downward and into and through theOven to the stacl,wliereas, by opening the oven door 19, and thuspermitting the damper 26 to drop to open position, a sufficient quantityof the hot gases is ley-passed through the dampenbox 25 to the stach tocreate an up-clraft therein quickly, and the desired circulation aroundand through the oven is established in much less time, and with muchless expenditure of fuel, than would be the` case if provision were notmade for such bypassing. Also, when the stove or range is in use, andaccess to the interior ofthe oven is desired, the automatic opening ofthe damper 26 when the ovendoor is opened, minimizes the quantity of hotgases that escape through the oven-door opening, and the `quantity ofcold ai1 that is drawn into thev oven therethrough, and results in thetemperature of the oven being maintained substantially uniform until theoven door is again closed.

Various modiiica-tions of minor details of the improvements shown anddescribed herein doubtlessy readily will suggest them'- sclves to thoseskilled in this art, but such modifications fall within the scope of myinventive rights, and my invention is not to be construed as beinglimited toany details not specihcally set out in the claim.

Having thus fully disclosed the invention, what I claim as new, and seekto secure by Let-ters lfatent, is

in ay stove having an oven placed below the top thereof, leaving apassageway for hot gases between said oven and said top, the combinationof a gas-outlet flue, an opening into said flue from said passageway, adamper in said opening, and secured to a shaft, bea-rings for said shaftarranged exteriorly of the flue, adoor to said oven, means operable bymovement of saidv door to retain said damper'in its closed position. anda counter-weight secured to the damper shaft eXteriorly of the flue formoving said lftlamper by gravity to open position when released by theopening of said door.

In testimony whereof I atiix signature.
